Fujifilm Sonosite Introduces New 46 MHz Transducer for POCUS

July 24, 2025 — Fujifilm Sonosite, Inc., a leader in point-of-care ultrasound (POCUS) solutions, has announced a new advancement in point-of-care ultrasound imaging with the introduction of their UHF46-20 Transducer. This new transducer is the first 46 MHz ultra-high frequency (UHF) transducer available today in the point-of-care ultrasound market.¹ 

With a minimum scan depth of 4mm, the UHF46-20 Transducer will enable clinicians to clearly visualize the first one to two centimeters beneath the skin and identify structures smaller than 1mm, such as superficial nerves and vessels, with high-quality resolution. Built upon the advanced Ultra High Frequency technology from Fujifilm VisualSonics, and available exclusively on the Fujifilm Sonosite LX POCUS system, this innovative technology provides the best superficial imaging^2,3,4 available on any point-of-care ultrasound system¹.

“At Fujifilm Sonosite, we are driven by a commitment to help solve real-world challenges clinicians and providers face. The UHF46-20 transducer, when paired with the Sonosite LX system, enables the largest frequency range of any point-of-care ultrasound system on the market today - addressing a longstanding challenge that current clinical ultrasound systems have been unable to overcome,” said Richard Fabian, president and chief executive officer of Fujifilm Sonosite, Inc. “We’re proud to bring to market the UHF46-20 Transducer as the first and only 46MHz UHF transducer in POCUS to provide clinicians with an unparalleled tool that may help them enhance diagnostic confidence and procedural accuracy.”

The combination of the new transducer and the Sonosite LX offers clinicians a versatile solution for a wide spectrum of imaging needs, spanning from deep abdominal scans to ultra-high resolution superficial assessments. The UHF46-20 Transducer holds promise for improving outcomes across a range of sensitive applications including Neonatal Intensive Care Unit (NICU) and Rheumatology. In the NICU, its superior resolution may help clinicians see superficial submillimeter anatomy that conventional ultrasound may not capture.^6,11 The use of UHF ultrasound may aid clinicians in improving procedural quality by allowing for better visualization of tiny anatomy that may help to improve first attempt success rates.^4,8,9,10 In Rheumatology, UHF’s advanced superficial imaging may aid in the visualization of subclinical synovitis, erosions, crystal deposits, and inflammation, all of which are beneficial in the early diagnosis and intervention of chronic conditions.^2,3,7
